Ronco RV Holding Tanks

The Ronco Plastics B156 is 50 gallons in a 40 x 20 x 16 inch block, and it is deliberately two tanks in one tooling. As part of Ronco's marine water / waste series, the molding is finished to...

Seven inches tall, 48 gallons. The B229 is the extreme end of the low-profile art: a 68.5 x 27 x 7 inch panel of a tank that lies flat where no conventional tank fits at all - under cockpit soles,...

Fifty-two gallons in a 28" x 23" x 21" block, and the choice of what runs through it left entirely to you: the Ronco Plastics B295 is a dual-purpose marine and RV molding that Ronco finishes either...

Forty-eight gallons in an 11-inch-tall package: the Ronco Plastics B306 is a broad, low dual-purpose molding - 45.5" x 24.25" x 11" - that carries real capacity in the horizontal spaces boats and...

Fifty gallons that hides in the bilge: the Ronco Plastics B308 spreads its capacity across a 64" x 22" x 9.12" slab, one of the longest low-profile dual-purpose moldings in the B-series. Marine or...

Fifty inches long and 16 x 16 in section, the B416 is the tank you run fore-and-aft along a keel line or tuck against a stringer where a boxier 50 gallon shell would never fit. The long, narrow...

Eleven and three-quarter inches of height is the headline on the Ronco Plastics B465. This 50 gallon dual-role tank spreads its capacity across a 59.75 x 18.5 x 11.75 inch footprint, long and...

Start with the arithmetic: 60 gallons of waste water weighs about 500 lb. That number, not the gallon figure, is what the 82H asks of your coach - a quarter ton of sloshing load that has to ride on...

The 87H is the heavy-wall option in Ronco's five-shape 45-gallon holding bench: 41 lb of polyethylene before any waste goes in, the most material of the group. For a tank that will spend its life...

The 26W is what balance looks like in polyethylene: 31 gallons in a 31 x 23 x 11.5 inch slab - not the longest, not the flattest, just proportioned so that one tank handles the water for a mid-size...

An S-shaped tank exists because the floor of a coach is not an empty rectangle. Frame members, axles, and plumbing chases carve the underfloor into odd channels, and the 80H is molded to snake...

The 81H turns a corner. Where most holding tanks are rectangles, this 62-gallon molding is drawn as an L, letting it occupy the dead space beside a wheel well or wrap the back of a step - underfloor...
